Compare any two graphics cards:
GeForce 9600 GSO 512MB vs Radeon HD 3870 1GB
IntroThe GeForce 9600 GSO 512MB has a GPU core speed of 650 MHz, and the 512 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also is comprised of 96 SPUs, 48 TAUs, and 16 ROPs.Compare that to the Radeon HD 3870 1GB, which has a core clock frequency of 775 MHz and a GDDR4 memory frequency of 1125 MHz. It also uses a 256-bit memory bus, and uses a 55 nm design. It is comprised of 320(64x5) SPUs, 16 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 3870 1GB should theoretically be much better than the GeForce 9600 GSO 512MB overall. (explain)
Texel RateThe GeForce 9600 GSO 512MB is much (approximately 152%) faster with regards to texture filtering than the Radeon HD 3870 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the Radeon HD 3870 1GB is superior to the GeForce 9600 GSO 512MB, though only just barely. (explain)
Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be moved across the external memory interface in a second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
